My invention relates to improvements in screens, more particularly to thosehavinga framemade almost wholly of metal.

Theobject of the invention is to providean improved screen frame consisting of rolled metal sections, which may be] shipped:

knocked down and readily assembled, and

whichis unusually well reinforced at the j corners without soldering and which permits 1 ready installation or renewaljof the; wlre screen cloth.

In the accompanying drawings, I have 111115 tra-ted several embodiments of the invention.

Figure 1 is a perspective view of a corner of a screen.

Fig. 2 isa similar view showing some of the parts separated to. illustrate the manner of assembly. t y L h Fig. 3-is an elevationoi a screen long enough to cover the entire. Window. I

Fig l is an enlarged perspective View of the central part of theframe thereof; g Fig. 5, is a cross-section of a modified form ;.offrame. Figs. 6, 7 and 8 are sections of further modifiedforms, and I i Q g ,Fig. 9 is an enlarged section ofa window 'frame showing the relation ofthe. screen, sashes, and a metal channel in which the screen slides.

The main rectangular in cross-section with a 'rabbet on 7 one side; The section is made uppreferabIy of'two strips ofsheet metal, one, of which 10 flanges of unequal length, the longer flange being bent parallel to the base and also in- Wa rdly with a short e dgelying parallel to said base. The shorter flange is preferably bent inwardly tofOrm an acute angle. The other strip 11 ofsheet metal is-bent, as shown in Figs'l and 2, to fit within thepartial ei1'-- closureformedby the first strip and closing the opening; Bothstrips' of metal are prefa 4 erablyprovided with longitudinal grooves,

each other at the mitered ends,.but are held very rigidly indesired relation bya plateor part of the frame is generally isyrolled to form a channel member with" the inner strip 10 beinggrooved or corrugatedto stiffen it, and the outer strip 11 being.

filler 12 having two. extending atright anglesto each other with opposite.

edges 13t'urned-up to form a channel. These flanges 13are of such a length as to fit snugly within the enclosure formed by the metal strips ,10, 11, asindicated in dotted lines atthe left hand end of Fig. 2. Each corner plate.

provided preferably with astruck upridge having a pair of small openings 15 there.- 1n to receive. screws 16 or other suitable fas--.

tening means. Each screw passes ,.thr0ugh an opening located to receive it in the strip 11.

A pair of additionalopenings.17. is also provided to rece ve screws 18, hereinafter referredto. g ,7 -;In order to holdthewire screen to theframe, the; metal fastening strip 19 is provrded, having the general form of a channel with the flanges bent'toward each other parallel to the base and then bent at right angles to form projecting edges, as shown in Figs. 1 and 2. When the parts are assembled, said edges are received within corresponding" grooves in themetal strip 11. A. wooden filler strip 20 is located within the channel '7 formed by the strip 19. The screws 18 ass through suitably spaced openings in the ase ofsaid channel and in the woodenfiller, and

also pass through the meshes in the screen and]; 7

through suitable openings in the metal strip 1 1. With thisarrangement, it will be seen that the projecting edges 21 pressthe screen 22 into the corresponding grooves and clamp the screen tightly in place. shape "of the completed cross-section is rectangular with ornamental grooves on their inner and outer faces, although thisrectangular section is not essential.

The general In order to raise the screen, one or more handles 23 are securedto the upper part of the horizontal member of the frame, each handle being formed preferably from a single sheet 1 ofmetal having downwardly bent ends se cured. to the frame and having the middle portion bent over, forminga guard 24 tojpro tect the; screen from damage caused by thrusting the fingers too far'under the handle. saidportion'also maybe stampedwith a designatingnumber. i V

The complete frame is rectangular in outline and 1s usually of a slze corresponding to,

the lower sashl of the window.) However,
